export button on masterpage to save gridview results from multiple content pages

Hi everyone,

New at this .net stuff but this seems logical: is it possible to have an export (to excel) button on the master page which saves query results from gridview in different content pages? As an example,

Query1.aspx & Query2.aspx

Each website has it's own query results displayed in gridview after hitting submit button from their individual pages.

From the Master Page, have an extract button which will save results of gridview depending on which website I am currently viewing.

Currently, I have extract button which works on each individual website but given the fact that I will have more queries and hence content pages in the future I thought it would be logical to have it on the master page which would save me a little work and maintenance?

Any suggestions would be awesome!!!

Thanks,

Stan Ho
